Make a Pokémon team for each generation. At the end create your team with 1 Pokémon from each Pokémon generation.

Rules:
>start with your favorite Pokémon from that generation
>Pick your second favorite Pokémon from that generation, but you can't choose a Pokémon whose type you already have in the team
>e.g. I have Blastoise, now I can't choose Poliwrath anymore
>if you choose a mega with a different type than the non-mega version, include all types as being in the team
>e.g. Charizard X counts as Fire, Flying and Dragon
>in the last team, pick 1 Pokémon from each generation and start with your favorite, than second favorite from those that are left, and so on
>e.g. I pick Blastoise, now I can't pick any water or gen 1 Pokémon anymore for the team

hard mode: no legendaries

You'll be sad who doesn't become a team member and surprised at who does.

You're the grand champion of all regions. Your team consists of 1 Pokémon from each generation with a nice type variety. You have trained all your Pokémon to the max!. Suddenly some faggot comes up to you and challenges you to a fight. He has Landorus-T, Greninja, Charizard X, Scizor, Rotom-W and Latios. Can you win?
